Struct EulerMethod 

Source 
pub struct EulerMethod {
    pub h: f64,
}
Expand description

Single-step Euler method solver.

Fields§

§h: f64

Step size h

Implementations§

Source§

impl EulerMethod

Source

pub fn new(h: f64) -> Self

Create with the given step size.

Source

pub fn step(&self, f: &dyn Fn(f64, f64) -> f64, t: f64, y: f64) -> f64

Perform one Euler step: y_{n+1} = y_n + h f(t_n, y_n).

Source

pub fn solve_to( &self, f: &dyn Fn(f64, f64) -> f64, t0: f64, y0: f64, t_end: f64, ) -> Vec<(f64, f64)>

Solve from t0 to t_end, returning (t, y) pairs.

Source

pub fn global_error_o_h(&self) -> f64

Global error is O(h): returns h as a proxy for the error constant.
